SPECIFICATION forming part of Letters Patent No. 357,348, dated February 8, 1887. Application filed April 3, 1836. Serial No. 197,618. (No model.)

To all whom it may concern.-

Be it known that I, LIONEL SHERIDAN TROTTER, of Portsmouth, in the county of Scioto and State'of Ohio, have invented a new and Improved SofaBed, of which the following is a full, clear, and exact description.

My invention relates to beds, particularly to beds of that class adapted to be unfolded for use as a bed and to be folded for use as a sofa or chair; and the invention has for its principal objects to provide a simple ineX-. pensive bed of this character, and also to provide for the concealment of the bedclothes within the bed-frame.'

The invention consists in certain novel features of construction and combination of parts of the bed, all as hereinafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a sofa-bed, showing it in full lines as. adjusted for a bed and in dotted lines as adjusted for a sofa; and Fig. 2 is a plan View partly broken away and in section.

The sofa-bed is made with three frames, A B O, hinged to each other at a b. The frame A forms theheavy seatframe of the sofa, while the other two frames, B O, are much lighter to allow them to be adjusted easily, to form either a bed or a sofa, as hereinafter explained.

All three frames A B C are provided with the woven'wire mattress material D, which may have support from below by springs of any form placed on the cross-slats cl ofv the frames. At or above the hinging-place b, between the frames B O, the mattress D is divided, as at d, to allow folding of the frames B 0 together in adjusting the piece of furniture. Above the mattress D any ordinary hair or other mattress, E, is placed, and these mattresses form the u pholstcry and will be covered with any preferred material for a pleasing finish, and preferably will have interior springs, giving them any preferred degree of elasticity.

At opposite sides of the bed there are pivoted, preferably on the pins of the hinges at b,

i the legs F F, and at the outer ends of the sides of framesOthere are pivoted the opposite legs, G G, the pivots of these legs G being about in line with the end journals of a roller, H, which is supported in and across the frame 0 as a guide to the bedelothing, and as presently explained. The legs F G at each side of the bed are connected pivotally by a bar, I, and the leg F at one side of the bed is connected pivotally to the frame A by a bar, J, and the leg F at the other side of the bed is connected pivotally to one end of a bar, K, the other end of which connects rigidly to the squared inner end part of a short shaft, k, journaled in the frame A, and having a squared outer end or head, k, to which'a wrench or crank, L, may be applied. frames B O are lifted where they are hinged to each other at b, and brought to the positions indicated in dotted lines in Fig. 1, the tie-bars I I J K will cause the legs F G to assume the positions there shown, the legs G then serving to support the back-frame from the floor.

The legs G will have caster-wheels g to roll on the floor as the bed is adjusted, and casterwheels will also be placed under the main seatframe A. Should it be preferred to do so, the frames B C may be raised to adjust the piece of furniture for a sofa or lowered to adjust it as a bed by turning the crank-lever Lwhen it is applied to the end of shaft is.

Beneath the front part of the seat-frame A there is'journaled to it a roller, M, 011 which is placed a spiral spring, N, one end of which is fastened to the roller at n and the other end to the frame A at n, and to enlarged parts or barrels m m of roller M there are fixed oneend of each of the cords O O, which are wound on the barrels m m and connect at their other ends with across-bar, P,to which are held the clampbars R R, which are adapted to hold securely between them one. end of the bedclothes S. The cords O O, and also the bedclothes, are adapted to pass over the roller H and between the cross-bars d of frames B O, and a bottom lining, T, applied to said frames, supports the the bedclothes andexcludes dust therefrom. The roller M is provided at one end with a ratchet, U, with which a spring-pressed pawl, V, hinged to the frame A, is adapted to engage WVith this construction, as the to prevent turning back of the roller, and the shaft of pawl V has a lever or arm, o, fixed to it outside of the frame A, by which arm the pawl may be lifted from the ratchet U. The shaft of roller M also has a squared end, m, to which the wrench L is adapted.

The spring N on roller M acts normally to wind the cords O 0 on the roller, and thereby draw the bedclothes S under or within the frames A B (J, which position the bedclothes will have when the piece of furniture is ad justed as a sofa; and when the bed is to be used the sections B G will be let down flat, and the ends 8 of the bedclothes S then may be taken hold of to draw the clothes from inside the bed and turn them up over the top of the upholstery E as the cords O unwind from the roller, the spring N thereby being put in tension. The pawl V will prevent the springroller from drawing the clothes back beneath the bed. A board, \V, which had been held in slidewaysw in the seat-frame A, will now be set up at the head of the bed, and the pillows X, which had been concealed beneath the frame A on the board WV, will be put in place, and the bed is ready for use. The clamps R It hoid the hedclothes securely to cover the feet of the occupants of the bed.

To adjust the bed as a sofa, the bedclothes S will be smoothed out flat and turned over at their side edges, and by releasing the pawl V from the spring-roller ratchet U the roller will automatically wind the cords O O on it, and thereby draw the bedclothes S back beneath or within the frames of the bed.

Should the roller-spring become weak, the

. crank-lever L may be applied to the end m of the roller to assist the spring in drawing the bedclothes to their place of concealment. The head-board \V and pillows X may again be placed within the seatframe A and the frame B G be raised, and the sofa is again ready for use.

It is evident that every part of the sofabed, also the bed-clothes, are open to free ventilation; hence the sofa-bed will remain in good con .on however it is used.

Arms any approved design maybe fitted to the .ids of the seat'frame A, so as to be fold down when the bed is used and raised l the sofa is used. .he sofa-bed may be made in different sizes or double or single beds, and so that when folded it may make a two or three seat sofa, or an arm-chair, as will readily be understood.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 7 1. A sofa-bed made with a seat frame, A, and folding back-frames B O, hinged together at a b, pivoted legs F G on frames B G, and

bars connecting said legs pivotally to each other and to the seat-frame A, substantially as and for the purposes herein set forth.

2. The combination, in asol'a-bed, of aseatframe, A, and folding back-frames BO, hinged together at a b, pivoted legs F F G G, bars I J, connecting the legs F G pivotally at one side of the bed with each other and with the seat-frame A, a bar, I, connecting the legs F G pivotally to each other at the other side of the bed-frame, a shaft, k, adapted to receive a crankdever and journaled in the seat-frame A, and a bar, K, connected pivotally to the last above-named leg F, and connected rigidly to the shaft is, substantially as shown and described, whereby the back frames B G and legs F G may be folded or unfolded by turning the shaft It, as set forth.

8. The combination, in a bed, of a roller, as at M, journaled in the bed-frame, cords O, connected to said roller, and hedclothes, as at S, connected to the cords, substantially as shown and described, whereby a turning of the roller will wind the cords on it to draw the .bedclothes to a place of concealment beneath or within the bed franle, as set forth.

4. The combination, in a bed, of a spring-- roller, as at M N,journaled in the bed-frame, a detent adapted to prevent turning back of the roller, cords 0, connected to said roller, and bedclothes, as at S, connected to the cord, substantially as shown and described, whereby on releasingthe detect of the roller it will automatically wind the cords on it to draw the bedclothes beneath or within the bedframe, as set forth.

5. The combination, in a bed, of a roller,

M, journaled in the bed-frame, cords 0, connected to the roller, hedclothes, as at S, connected to the cords, and a roller, H, journaled across the end of the bed for the cords and bedolothes to draw over, substantially as herein set forth.

6. The combination, in a bed, of a roller, as at M,journaled to the bed-frame, cords 0, attached to the roller, bedclothes S, attached to the cords and adapted to bedrawn by them and the'roller within the bed frame, and a bottom, T, supporting the clothes in the be lframe, substantially as herein set forth.

7 The combination, in a bed, with a roller, as at M, journaled to the bed-frame, cords 0, attached to the roller, bedclothes S, attached to the cords, and means for operating the roller to wind the cords on it, of clampbars, as at BB, held to the cords, substantially as herein set forth.
